Punctuation: numerals and punctuation
In British English the date is usually given in the order day, month, year.
We use full stops in dates. Forward slashes or dashes are also commonly used:
Date of birth: 1.8.1985 (or 1/8/1985 or 1–8–1985)
In American English the day and the month are in a different order so that 8 January 1985 is written as follows:
1–8–1985 (or 1/8/1985 or 1.8.1985)
We don’t usually punctuate weights and measures and references to numbers:
4kg (4 kilograms)10m (10 metres) 5m dollars (5 million dollars)
Commas are used in numbers to indicate units of thousands and millions:
7,980 (seven thousand, nine hundred and eighty)
11,487,562 (eleven million, four hundred and eighty-seven thousand, five hundred and sixty-two)
We use full stops, not commas, to indicate decimal points:
6.5 (six point five)
Not: 6,5
We can punctuate times with full stops or colons:
The shop opens at 9.30. (or 9:30)
